1 Claim.

The present invention appertains to new and useful improvements in shade rollers of the type containing a spring and shaft and wherein the shaft is journaled through a cup plate or like end member.

An important object of the present invention is to provide a readily removable cup plate which can be readily removed from the roller to permit access to the spring and shaft, to the end that repairs and replacements can be made more readily than is now possible with the conventional roller construction. I

Another important object of the invention is to provide a shade roller of sheet metal construction, thus enhancing lightness in weight and perhaps economy of construction without sacrificing strength.

Still another important object of the invention is to provide a shade roller of sheet metal construction which promotes not only lightness in weight, resistance to wear, and other factors, but principally increases durability.

A further object of the invention is to provide a shade roller constructed of metal, plastic, or some other material capable of being formed with threads at one end to receive a threaded coupling, which can be readily removed when repairs and replacements of internal parts become necessary.

Still a further object of the invention is to provide a shade roller wherein either one or both end plates can be constructed to permit removability, without sacrificing the normal strength of the roller and definitely increasing accessibility to the internal elements of construction.

Various other important objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 is a fragmentary of the improved roller.

Figure 2 is a fragmentary longitudinal sectional view through the improved roller.

Figure 3 is an end elevational View of the roller showing a portion broken away.

Figure 4 is an enlarged fragmentary detailed sectional view taken on line 44 of Figure 1.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that numeral 5 denotes the roller proper which consists of an elongated cylindrical shell preferably of a metallic alloy, but which can be of some plastic material, or other material suitable for the purpose, and which can be moulded or otherwise formed to provide an elongated trough 6 for reside elevational view 2 ceiving the usual hem I and contained rod or anchoring element 8 of a window shade 9.

A shade roller includes a shaft in and a spring H. One end of the roller generally has a round or cylindrical pintle, while the distal end of the roller and more specifically the corresponding end of the shaft it] has a key or flattened extension I2. This end of the shaft I0 is normally journaled through a cup plate, but in the instance of the present invention, numeral l3 denotes a cup plate, the peripheral portion of which is formed with threads coefficient to internal threads 14 formed within the adjacent end portion of the roller 5.

More or less conventionally the shaft H1 is provided at the outside of the cup plate l3 with a formation l5 formed with recesses or shoulders with which pawls l6 are cooperative, obviously to prevent the return movement of the shade roller.

It is preferable that the roller 5 at opposite sides of the trough 6, at the cup plate end thereof (or at each end should both end plates be removable) be formed with openings to accommodate set screws l! which can be driven into threaded openings in the peripheral portion of the roller 5. Thus it can be seen that with the set screws located adjacent to and at opposite sides of the trough 6, the trough construction will be reinforced and definitely determined with respect to expansiveness.

It can now be discerned that the principal purpose in able is so that ready access can be obtained to the interior of the roller in order that the internal parts can be removed for the purpose of repairs or replacements.

Obviously, by removing the set screw H, the end plate I3 is freed to the extent that it can be unscrewed from the roller 5, thus freeing the shaft l0 and spring I I so that these parts can be replaced or repaired as the occasion demands While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
